python爬虫遇到问题

[Real1009]

用xpath获取的url为['/D/Periodical_zgxzgl201705021.aspx', '/D/Thesis_Y2069101.aspx']，请问如何在前面加上域名，变成
[http://lib-wf.sstir.cn/D/Periodical_zgxzgl201705021.aspx ,http://lib-wf.sstir.cn/D/Thesis_Y2069101.aspx ]这样的呢

newUlr=[]
for item in url:
	newUlr.append('http://lib-wf.sstir.cn/'+item)
print(newUlr)
